Not to hijack RB's thread, but in SC we don't have deep freezing ground to heave up and distort buildings. Builders can get away with setting a building on blocks, if that is what that one had. There is an underlying layer of red clay which can do a good imitation of concrete in the upstate. Low country has sandy soil but still has a clay layer of some sort.
Also, I don't think RB mentioned the condition of the building. It may well have had issues, not that SC contractors would build shoddy buildings, of course!!?
